/* 2026-10-02 — TUTORIAL GUIADO v2 (site, onda 1; assets/tutorial.js). Só tokens do tema (claro/escuro): --panel --text --muted --line --accent.
   Camadas: o player é um <dialog> modal (topo da pilha; fundo inerte); o recorte é uma caixa com sombra gigante (a camada escura NÃO usa blur).
   Vidro no iPhone (html.zk-glass): balão, pílula e convite translúcidos com desfoque; prefers-reduced-transparency → sólido.
   Movimento: transição do recorte .35s; "Remover animações" (html:not(.zk-anim)) e prefers-reduced-motion → tudo salta; demos paradas no último quadro. */
